Tracking polls

Answer 2

"What is a tracking poll?"

"Each night between September 2 and the election, Gallup will conduct interviews with registered voters. Each day until the election, CNN will report the results from the previous two nights. To do so, we will drop the oldest interviews to make room for the most recent ones. In other words, on Thursday we will report the results of the interviews conducted Tuesday and Wednesday. On Friday, we will drop the Tuesday interviews and report the results of the interviews conducted Wednesday and Thursday. On Saturday, we will report the results for Thursday and Friday -- and so on."

"In tracking polls, the trend counts as much as or more than today's numbers. Tracking poll results reflect an overall pattern of campaign events that are unfolding day by day. This is why AllPolitics always reports the trend across a week or more, rather than just one day's numbers."

"If ordinary polls are snapshots of the electorate, tracking polls present a moving picture. But out of context they make no more sense than a single frame from a movie. One example: One week the CNN/USA Today/Gallup tracking poll showed results which included Wednesday and Thursday -- which were two good days for Dole -- and also included Saturday and Sunday -- two good days for Clinton. During that time, the tracking poll accurately reported Clinton's lead ranging from 9 to 22 points. If we had done a regular poll over those four days, we would have shown a 16-point lead -- almost identical to the 15-point lead in an ordinary (non-tracking) ABC poll conducted on those same days."

"Day-by-day the tracking poll can only show temporary gains or losses attributable to temporary events. Week-by-week, the tracking poll shows remarkable stability: an 18-point Clinton lead in the first week of September, a 17-point lead in the second week, and 16-point leads in the third and fourth weeks."
